This review is from: ScreenDim Full (App)
I had the 3 day trial first which was ok but it took time to get used to - for example it will stop working (on an android phone at least) when your phone has been to sleep and then woken up again - so you have to make sure you have the settings right or it will not be working most of the time! Also (and there is no setting to change this as far as I know) this app doesn't start automatically when the phone is switched on so you have to start it up yourself. However, as soon as I had these things figured out it was great - I could reduce the screen brightness by lots - I didn't realise how bright it was (and didn't need to be) until I got this app! Instead of my phone being charged every 20 hours or so it now lasts for over 2 days. Pleased with the results.
